Open BiatuAutMiahn opened 7 years ago

BiatuAutMiahn commented 7 years ago

Hello, I am attempting to set the contrast/brightness on this, but it does not seem to respond to the command.

Thank you

Development has moved forward to u8g2. Can you check with u8g2?

BiatuAutMiahn commented 7 years ago

I would use u8g2, however it does not support grayscale on my module. or at least I was unable to see grayscale in any of the demos

olikraus commented 7 years ago

You are right, u8g2 does not support grayscale any more.

You could change the code by yourself.
